ETHEX Corporation Initiated Nationwide Voluntary Recall of a Single Lot of Hydromorphone HCl 2 mg Tablets Due to Potential for Oversized Tablet

St. Louis, MO – December 23, 2008 – ETHEX Corporation announced today that it has voluntarily recalled to the consumer level, a single production lot of Hydromorphone HCl 2 mg tablets (Lot #90219, Exp: 03/2010; NDC #58177-0620-04), as a precaution, due to the possibility it may contain oversized tablets. Hydromorphone is a drug used for pain management and is packaged under the ETHEX label in 100-count bottles.

If someone were to take a higher than expected dose of Hydromorphone, the risk of adverse effects known to be associated with the drug may be increased, including respiratory depression (difficulty or lack of breathing), low blood pressure, and sedation.
